Definitions

  • the invention relates to a one-hand soldering device with a soldering iron with an electrically heated soldering tip and a solder wire feed, through which solder wire is fed to the soldering tip, the feed ending in a tubular mouthpiece that is movable relative to the soldering tip.
  • the tubular mouthpiece is flexible and is attached to an arm which allows the free end of the mouthpiece to be adjusted in the longitudinal direction of the soldering iron, so that the free end of the mouthpiece is always in the Can be brought near the end of the soldering tip, even if soldering tips of different lengths are used.
  • the supply of the solder in the area of the soldering tip is critical, however, since the end of the solder protruding from the mouthpiece must not be arranged too close to the hot soldering tip, since otherwise the flux can leak and drip from the solder wire.
  • the invention has for its object to provide a one-hand soldering device of the type mentioned, in which the tin supply to the hot soldering tip is improved.
  • the feed is designed as a tube that a spring acts on the mouthpiece, which holds the mouthpiece in a predetermined position, and that the mouthpiece is shaped so that in the undeflected state of the spring that from the Mouthpiece protruding end of the solder wire is held at a distance from the soldering area of the soldering tip.
  • the end of the soldering device protruding from the feed pipe or the mouthpiece is always at a sufficient distance from the hot soldering tip in the idle state, so that there is no risk of the flux dripping out.
  • the solder wire is advanced using known devices under the control of, for example, a switch on the soldering iron, and during the actual soldering process the soldering iron is guided so that the solder is between the workpiece and the hot soldering tip. Due to the action of the spring, the solder wire first lies on the workpiece and is then heated by the depressed piston, because when the piston is pressed down, the mouthpiece is deflected from its rest position against the action of the spring and there is contact between the solder wire and the hot soldering tip.
  • solder wire, the flux and the soldering tip are together at the soldering point and when the solder melts, the free end of the solder wire automatically returns to the rest position due to the action of the spring.
  • the embodiment of the one-hand soldering device shown in the drawing consists of a soldering iron 1 with a soldering tip 2 which is attached to the end of a heating element 3. Solder wire is advanced with the aid of a not shown, known per se solder feed device through a feed tube 4, which is connected adjacent to the soldering iron 1 with a rigid end piece 10, which is attached to the soldering iron 1 via a fastening tab 6.
  • a clamping piece 8 is pushed onto the tubular rigid end piece 10 of the feed pipe 4, which can be fixed in a predetermined position on the end piece 10.
  • the clamping piece 8 carries one end of the spring 7, which according to FIG.
  • the clamping piece 8 has a forwardly extending projection which, provided with a threaded bore, cooperates with the rear end of the mouthpiece 5 in order to fix the starting position of the free end of the mouthpiece 5 and thus the position of the portion of the solder wire 11 which projects from the mouthpiece.
  • the method of operation of the one-hand soldering device described above is as follows:
  • the solder wire is advanced according to the setting of the device, for example by actuation by a switch installed on the soldering iron, so that one end of the solder wire 11 protrudes from the mouthpiece 5 and lies adjacent to the soldering tip 2 .
  • the soldering iron is guided in such a way that the solder wire initially rests on the workpiece, whereupon the soldering iron is pressed down in order to bring the solder wire into contact with the soldering tip 2.
  • the mouthpiece 5 interlocks against the action of the spring 7 in the direction of the soldering tip or the heating element of the soldering iron.
  • the mouthpiece 5 When the solder melts under the action of the hot soldering tip, the mouthpiece 5 is released again and moved by the spring 7 at a distance from the soldering tip, so that the drainage of the flux from the soldering wire is largely prevented, since the free end of the soldering wire is in an area is moved, which is no longer too high.
